The Pope's Exorcist stars Academy Award winner Russell Crowe along with a diverse cast of actors from all over the world. Crowe plays the titular character, Father Gabriele Amorth, a real-life Catholic priest who claimed to have performed tens of thousands of exorcisms in his career. Drawing inspiration from Amorth's own memoirs and case files, The Pope's Exorcist deals with Amorth's battle against several demons, who possessed innocent people. As the Chief Exorcist of Vatican investigates the case of a possessed boy, he also comes across an ancient conspiracy that the Catholic Church has tried to keep hidden for centuries.
